API Question

[Anonymous]

I'm slogging my way through the server API and keep running across things that I can't find any reference to. For example, this line of code:

$queryOptions->SetSpatialFilter('SHPGEOM', $bufferGeometry, $MgFeatureSpatialOperations::Inside);

makes reference to "SHPGEOM". Where in the documentation can I find out more information about what options I can use with SetSpatialFilter? If I wasn't using Shape files, what would I substitute in place of SHPGEOM?

Thanks - Jack

SHPGEOM is the name of the property/column in the Feature Source (shape file) that stores the geometry data.

Basically you would substitute SHPGEOM with the name of the geometry property of your Feature Source

Jackie,

Thanks for replying. That make senses, but where do I find what that name would be? When I look at the layer in Studio, for the Geometry of a layer sourced by a Shape file it says "Geometry", not SHPGEOM. What I look at a layer sourced by an SDF, it says "Data". So when using an SDF would it be SDFGEOM? or SDFDATA?

Thanks - Jack

Those names are just the default names generated by MapGuide Studio / AutoCAD Map when you create new Feature Sources.

To get the name of the geometry property:

Get the matching class definition (MgClassDefinition) object for that feature source using MgFeatureService::GetClassDefinition

Calling GetDefaultGeometryPropertyName() on that class definition will give you the name of the geometry property.
